BACKGROUND OF THE INVENTION

1. Technical Field of the Invention

The present invention relates to wireless communication devices used for placing telephone calls over a wireless telephony network.

2. Description of Related Art

Wireless telephones are commonly used to place telephone calls over wireless telephone networks. Examples of such networks include wireless telephone networks that operate via services such as cellular, personal communications service (PCS), general packet radio service (GPRS), global system for mobile communications (GSM), and integrated digital enhanced network (iDEN). These networks are capable of accessing the plain old telephone service (POTS) network as well as broadband data networks that provide Internet access and enhanced services such as streaming audio and video, television service, etc., in accordance with international wireless communications standards such as 2G, 2.5G and 3G.

Handheld breath analyzing devices, commonly known as “breathalyzers”, are used to estimate the amount of alcohol in a person's blood. In many states, law enforcement personnel employ these devices to perform on-site sobriety tests of drivers suspected of being intoxicated. U.S. Pat. No. 7,341,693 to Der Ghazarian presents a radio frequency (RF) breathalyzer system, which transmits a unique RF signal in response to a toxic or non-toxic breath sample given to a RF breathalyzer by the user. An immobilizer CPU is installed in a vehicle to receive commands from the RF breathalyzer and to control a horn and lights of a vehicle, to immobilize the engine, and is connected to a GPS antenna driver through a mobile phone/pager unit to communicate with a monitoring station.

The disadvantages of traditional approaches will be apparent to one skilled in the art when presented the disclosure of the present invention as reflected in the enclosed drawings, claims and accompanying description.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 presents a pictorial representation of a wireless telephony device 50 in accordance with an embodiment of the present invention. In particular, a wireless telephony device 50 communicates over a wireless telephony network 70 that is operably coupled to a plan old telephone service (POTS) network and data network such as the Internet. In an embodiment of the present invention, wireless telephony network 70 includes a wireless telephone network such as a cellular, PCS, GPRS, GSM, iDEN or other wireless communications network capable of sending and receiving telephone calls text messages, such as short message service (SMS) messages, email or other data messages that may include multimedia elements such as documents, audio files, video files, images and other graphics.

In an embodiment of the present invention, the wireless telephony device 50 includes a breath analyzing sensor 25. When a user places a telephone call or receives a telephone call via the wireless telephone device 50, the breath analyzing sensor 25 analyzes the breath of the user as the user speaks into the wireless telephony device 50 in conjunction with the telephone call. In response, the breath analyzing sensor 25 generates breath analysis test data. The wireless telephone device 50 generates a breath analysis test message 60, such as an email or text message, based on the breath analysis test data and transmits the breath analysis test message 60 via the wireless telephony network 70.

The operation of wireless telephony device 50 can be described in conjunction with the following example. In this embodiment, the wireless telephony device 50 is a cellular phone provided by a parent for use by a teenage son or daughter. An email or text messaging address of the parent is stored in a memory of the phone during set-up of the wireless telephony device 50. When the teenager uses the phone, his or her breath is analyzed for alcohol content. A text message is sent to the parent, either for each call made or received only in circumstances when the estimated blood alcohol content is above a threshold that is either selected by the parent during the set-up of the wireless telephony device 50 or is pre-stored.

For instance, the parent requires the son or daughter to call home before leaving a party on a Saturday night. When the teenager is about to leave they call home using the wireless telephony device 50. If the teenager has been engaged in drinking, the breath analyzing sensor 25 generates breath analysis test data that indicates an unacceptable blood alcohol level. The results of this test are sent to the parent via a text message, either during the call or shortly thereafter. In response the parent tells the teenager during the call or calls the teenager back to inform the teenager that the teenager is not allowed to drive and that the parent will come and pick up the teenager and bring him or her home.

In particular, the telephony application provides functionally to send and receive telephone calls, text messages and email and to optionally browse the World Wide Web under commands of the user. In addition, the telephony application can generate and transmit automatically generated email and/or text messages in the form of breath analysis test message 60.

The processor of processor 100 can be implemented using a microprocessor, micro-controller, digital signal processor, microcomputer, central processing unit, field programmable gate array, programmable logic device, state machine, logic circuitry, analog circuitry, digital circuitry, and/or any device that manipulates signals (analog and/or digital) based on operational instructions that are stored in memory, such as memory 102. Note that when the processor 100 implements one or more of its functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the memory 102 storing the corresponding operational instructions may be embedded within, or external to, the circuitry comprising the state machine, analog circuitry, digital circuitry, and/or logic circuitry. The memory 102 may be a single memory device or a plurality of memory devices. Such a memory device may be a read-only memory, random access memory, volatile memory, non-volatile memory, static memory, dynamic memory, flash memory, cache memory, removable memory card and/or any device that stores digital information.

Wireless telephony device 50 further includes an RF interface such as an RF transceiver for wireless communication with wireless telephony network 70.

Breath analyzing sensor 25 can include a spectrophotometer such as an infrared spectrophotometer, electrochemical fuel cell or other gas analyzer that analyzes the breath of the user of wireless telephony device 50 to detect the presence and concentration of alcohols, such as ethanol and methanol, acetone or other hydrocarbons that indicate the blood alcohol level of the user. In an embodiment of the present invention, the breath analyzing sensor 25 is coupled to an orifice in the housing of wireless telephony device 50 used by the microphone included in user interface 106. In another embodiment, the breath analyzing sensor 25 is coupled to an orifice in the housing of wireless telephony device 50 that is in proximity to an orifice used by the microphone included in user interface 106. In either case, the breath analyzing sensor 25 is configured to analyze the breath of the user when the user is talking into the microphone during ordinary use in conjunction with a telephone call. While the breath analyzing sensor 25 is described above as being implemented in a permanent position within the wireless telephony device 50, in an embodiment of the present invention, the breath analyzing sensor 25 can be removableably connected to the wireless telephony device 50, via a port within the battery compartment or via an external port. Further the breath analyzing sensor 25 can be incorporated in a SIM card or battery used in conjunction with the wireless telephony device 50.

As discussed in conjunction with FIG. 1, an email or text messaging address of the breath analysis test message 60 is stored in memory 102 during set-up of the wireless telephony device 50. In addition, memory 102 stores a test threshold, such as 0.01%, 0.02%, 0.04%, 0.08% or some other blood alcohol level, that is either selected by the parent during the set-up of the wireless telephony device 50 or is pre-stored in the memory 102. This test threshold can be used to generate breath analysis test results, such as an indication of whether or not a particular blood alcohol level of the user passes or fails. In particular, the telephony application can compare the breath analysis test data the test threshold and generate breath analysis test results in response thereto. In this fashion, the breath analysis test message 60 can include the breath analysis test results.

In another embodiment of the present invention, the breath analysis test results can be used by the telephony application to trigger the transmission of a breath analysis test message 60. For instance, the breath analyzing sensor 25 can analyze the breath of the user during each call sent or received via the wireless telephony device 50. If the breath analysis test results indicate that the blood alcohol level of the user is above the test threshold, the breath analysis test message 60 is transmitted. However, if the breath analysis test results indicate that the blood alcohol level of the user is below the test threshold, no breath analysis test message 60 is transmitted. The conditions for sending a breath analysis test message 60, such as for every call, or only for calls where the breath analysis test results indicate that the blood alcohol level of the user is above the test threshold, can also be established during the set-up of the wireless telephony device 50.
